Orbital emphysema after transcanalicular laser-assisted dacryocystorhinostomy treated with needle decompression

ABSTRACT

Orbital emphysema is an abnormal presence of air in the orbit. It usually arises after blunt trauma or periorbital surgery. When it occurs after dacryocystorhinostomy, usually it is reported as a benign condition. We present a case of a severe orbital emphysema secondary to transcanalicular diode laser-assisted dacryocystorhinostomy. The day after the surgery, the examination revealed crepitant periorbital swelling, general restriction of extraocular motility, visual loss and intraocular pressure of more than 70 mmHg. A computed tomography showed a massive orbital emphysema. An emergency decompression, using a 25-gauge needle attached to an empty syringe lacking a plunger was performed, achieving a quick decrease of intraocular pressure and pain and swelling improvement. Then, in this case, orbital decompression by passive airflow using a needle without a plunger was an effective treatment method to resolve a serious orbital emphysema after transcanalicular laser-assisted dacryocystorhinostomy.
